  • e91df49fb   kbuild, blackfin: Add CONFIG_CC_OPTIMIZE_LIBS_FOR_SPEED ... Browse Code »

    Many (but not all) of Blackfin boards give -O2 option
    to compile under lib/ directory.
    That means lib/ should be speed-optimized,
    whereas other parts should be size-optimized.

    We want to keep the same behavior,
    but do not want to parse board/*/config.mk again and again.
    We've got no choice but to invent a new method.

    CONFIG_CC_OPTIMIZE_LIBS_FOR_SPEED, if it is enabled,
    gives -O2 flag only for building under lib/ directory.

    Dirty codes which I had marked as "FIX ME"
    in board/${BOARD}/config.mk have been deleted.
    Instead, CONFIG_CC_OPTIMIZE_LIBS_FOR_SPEED has been
    defined in include/configs/${BOARD}.h.

  • 6825a95b0   kbuild: use Linux Kernel build scripts ... Browse Code »

    Now we are ready to switch over to real Kbuild.

    This commit disables temporary scripts:
    scripts/{Makefile.build.tmp, Makefile.host.tmp}
    and enables real Kbuild scripts:
    scripts/{Makefile.build,Makefile.host,Makefile.lib}.

    This switch is triggered by the line in scripts/Kbuild.include
    -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj
    +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj

    We need to adjust some build scripts for U-Boot.
    But smaller amount of modification is preferable.

    Additionally, we need to fix compiler flags which are
    locally added or removed.

    In Kbuild, it is not allowed to change CFLAGS locally.
    Instead, ccflags-y, asflags-y, cppflags-y,
    CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o
    are prepared for that purpose.
